It would appear from the man page for rdist (at least, the version in
RedHat 7.0) that you can couple it with ssh as well. Of course, I have no
assumptions about whether or not this works in a similar fashion to how
rsync does it.

This is a feature of ssh that I was not aware of. I didn't know that the
authorized_keys could be used to restrict what commands are run and
prevent the session from getting a normal UNIX shell. I will have to look
at the OpenSSH docs to see if that feature is available in the latest
version.
